Description

Technical Field

[0001] The utility model relates to the technical field of wheelset rust removal and cleaning machines, and more specifically to an air path mechanism of a brushing mechanism of a wheelset rust removal and cleaning machine. Background Art

[0002] Before inspecting and maintaining the locomotive wheels, the wheels need to be derusted first. The quality of wheelset derusting is of great significance to ensuring the quality of the next process of flaw detection, reducing missed detection and wrong detection, and ensuring transportation safety. Conventional wheelset derusting methods mainly include shot blasting, wire wheel derusting, high-pressure water jet derusting, etc.

[0003] The invention of Chinese patent application number CN00111996.6 discloses an automatic rust removal and cleaning machine for wheel sets that imitates the shape of the wheels, which is composed of a rust removal and cleaning device for the axle body that imitates the shape of the wheels and a rust removal and cleaning device for the dust plate seat that imitates the shape of the wheels, wherein the axle body rust removal and cleaning device includes a door frame, a running mechanism, etc., and is characterized in that it also includes a profiling mechanism, a double lifting and slapping brush cylinder, an axle body cleaning frame, etc., and the dust plate seat rust removal and cleaning device includes a column, an electric motor, etc., and is characterized in that it also includes a dust plate seat lifting and slapping brush cylinder, a running profiling groove, a sliding shaft, etc. Since the present invention is designed with a profiling mechanism, it can thoroughly remove rust and clean the axle body and the dust plate seat, and has the advantages of low energy consumption, high efficiency, easy operation, and convenient maintenance;
